Ortho Tri-Cyclen - If I want my period to end can I stop the last 3 inactive green pills?

Will that work and just start the new pack and when would I start the new pack if I were to skip the green pills? My periods just last for 3 weeks and it's awful, Ive read if you skip the green pills you can skip your period so just thought I'd give it a try. This is week 2 on my period and I have 3 green pills left can I just not take them to make my period end early?
